I'm the team leader for the University of Manitoba SAE Formula Electric team (In Canada).
We currently have an I+ME Actia BCS (Battery Control System), consisting of 3 slave boards good for monitoring 10 cells each and the master board to control everything over isolated RS-485 communication. The master also has a CAN stream and RS-232 stream/interface for monitoring. see here:
This year we are upgrading to another BMS and are looking to get some extra funds by selling these parts. Please let me know if you are interested in buying.
Along with getting the parts, myself and a few other experienced members of our team would be happy to help out by answering any questions about building a drive train with these components.
We are looking for ~400$ for the lot.
